Bandwidth Enhancement Based on Optimized Via Location for Multiple Vias EBG Power/Ground Planes

Abstract:In modern printed electronics, the performances of a circuit and a device are severely deteriorated by the electromagnetic noise in the gigahertz (GHz) frequency range, such as the simultaneous switching noise and ground bounce noise. A compact and multi-stack electromagnetic bandgap (CMS-EBG) structure is proposed to suppress the electromagnetic noise over the GHz frequency range with a short distance between a noise source and a victim on multilayer printed circuit boards (MPCBs). The original configuration of the stepped impedance resonators is presented to efficiently form multiple stacks of EBG cells. The noise suppression characteristics of the CMS-EBG structure are rigorously examined using Floquet-Bloch analysis. In the analysis, dispersion diagrams are extracted from an equivalent circuit model and a full-wave simulation model. It is experimentally verified that the CMS-EBG structure suppresses the resonant modes over the wideband frequency range with a short source-to-victim distance; thus, this structure substantially mitigates GHz electromagnetic noise in compact MPCBs.

“…Compared with the typical slit-EBG structure, multislit EBG structure is more suitable for high-speed systems, though the principle of selecting the structure parameters is not clear [11]. Despite the multiple vias of mushroom EBG [12], ground surface perturbation lattice (GSPL) EBG [13], and defected ground structure [14] destroy the integrity of the ground plane, the inner layer makes the power distribution network (PDN) impedance decreases, and brings no complexity to the board-level design. Cascade EBG [15], [16], embedded planar EBG [17], and low-temperature cofired ceramic EBG [18] structure can reduce the noise and high-frequency components, but the structure are all difficult to manufacture, and not suitable for high-speed data acquisition system and practical applications.…”

Simultaneous switching noise (SSN) is verified as a serious impact on the quality of power distribution and accuracy of the data acquisition system in the mixed signal circuits by modeling and simulating the single-stage output buffer at the driver side. To reduce SSN, a board-level slit-surface disturbance lattice electromagnetic bandgap structure is proposed. The corresponding 1-D equivalent transmission line model is established and lower and upper bound cutoff frequencies of the bandgap are derived. Suitable test boards are fabricated and measured to demonstrate the accuracy of the design concept. The measured SSN reduced to 65% and the signal jitter is decreased by 75% comparing with the solid power/ground plane, which proves that the isolation between the analog and the digital signals can be enhanced to improve the quality of power distribution, and provides a new method to improve precision for data acquisition and transmission in power monitoring system. The results show that the simulated, modeled, and measured results are consistent.Index Terms-Electromagnetic bandgap (EBG), mixed-signal system, noise suppression, simultaneous switching noise (SSN), stopband enhancement.

“…Although one additional metal layer is required, the resonant via-or mushroom-type EBG structures can keep the power and ground planes solid compared with other planar EBG structures. The stopband bandwidth of them can be enhanced using multiple vias [10]- [12], defected ground structures [13], and interleaved ground patches [10], [14], [15].…”

“…This is quite time consuming because these 2-D EBG structures are usually of several guided wavelengths long on each side. To speed up the design process, equivalent-circuit models of unit cells using lumped elements and/or transmission lines have been proposed [6], [7], [12], [13], [15]- [18] to help predict the stopband behavior. On the other hand, only a little work has been done for the synthesis of the whole EBG structure based on the given specifications.…”

A systematic design method is proposed to achieve the optimal design of bandstop power delivery network (PDN) using resonant vias in a multilayered printed circuit board (PCB). With the proposed equivalent-circuit model, design equations, and design charts, the geometrical structure of a resonant viatype bandstop structure can be quickly designed according to the desired stopband bandwidth and isolation level. Wideband bandstop PDN designs using the resonant vias in standard fourlayer PCB are fabricated and measured to demonstrate the effectiveness of proposed design method.Index Terms-Noise isolation, power delivery network (PDN), resonant via.
